Is there a way to compile multiple input files into one output file via the command line? Currently I am using \include, but I would like to be able to choose the included file on the fly without editing the main file.
Another thought I had was maybe there is a way to pass a value to the .ly file via the command line and use Scheme to choose the appropriate file to import based on that value. But that may be even more far-fetched. Thanks for your help!
